IMPROVEMENT IN MACHINES FOR DIVIDING COUNTER 0R HEEL-STIFFENER BLANKS.

Specification forming part of Letters Patent No- 163,23l, dated May 11,1875 application filed March 15, 1875.

To all whom it may concern:

Be it known that I, STEPHEN Mooan, of South Sudbury, of the county ofMiddlesex and State of Massachusetts, have invented a new and usefulMachine for Dividing Gounter or Heel-Stifiener Blanks; and do herebydeclare the same to be fully described in the following specification,and represented in the accompanying drawings, of which- Figure l is atop view, Fig. 2 a side elevation, Fig. 3 a front View, and Fig 4 alongitudinal section, of it. Fig. 5 is a transverse section, takenthrough its feed-Wheels and cutter. Fig. 6 is a top view of the cutter,and Figs. 7 and. 8 are side views of the hooked plates for supportingtheknife and gaging its out.

This machine is to divide an elliptical or other proper shapedcounter-blank along its middle or longer axis into two counters or heelstiffeners and scarf or bevel, each along the chord of its arc.

Fig. 9 is a top View of one of such blanks, and Figs. 10 and 11 exhibitit as separated into two counters, each scarfed along its chord. Fig. 12is an end view, it showing the line of separation. I

In dividing these blanks it is necessary that each should be out alongits central axis, and that the bevel should extend in oppositedirections therefrom, and be of equal width throughout, as any variationtherefrom will produce an irregularity in the size of the counters,which is very objectionable.

In machines used heretofore for dividing leather on a beveled line, forwelts or similar uses, there has been no' means adapted to make thebevel a definite width. In some of such machines one edge of the cutteris so attached to the shaft of the feed-roll that it adjusts itself tothe yielding movement of the roll, but in splitting a hard material likeleather board, especially when it is quite thin, nothing like an evenbevel can be made; for in splitting leather board, as is often done,onesixteenth of an inch thick on a bevel of onehalf an inch wide, theedge of the cutter has to be so nearly parallel with thesurface of theboard that should the cutter spring or yield one-fiftieth of an inchvertically it would vary the width of the split counters one-sixth of aninch, or enough to spoil them for good work. These difficulties areobviated in my machine, which also provides means for conveying theblank or material to the feed rolls or rollers, and guiding it so as todivide ,it in in astraight path through its central axis.

My machine consists of two feed-rolls, A B, fixed upon parallel shafts OD, supported in and by a suitable frame, E. These shafts are gearedtogether, as shown at a b, so as to run in opposite directions. One ofthem may or should be applied so as to yield, to allow for varyingthickness of material when it does vary. On one side and partly betweenthe rolls is the cutter F, which, at its rear end, is held by astandard, G, or any suitable support. Near its cutting-edge the cutteris formed with shoulders, as shown at d cl, to enable it to be held bythe hooks e c of two hooked plates or gages, H I, arranged, as shown,with said cutter and the feed-rolls, and fixed to plates or levers K Lthat pivot upon the shafts of the rollers, and are provided with springsM N to so act against them as to force the hooks e 6 up to and maintainthem in engagement with the shoulders of the knife or cutter. Thefeed-rolls are each to he of the width of the scarf, the gage-platesbeing set up close against the opposite faces of the feed-rolls, asshown.

The arrangement of the cutter is such that one counter must pass overand the other under it, the blank being divided by such knife, so as tocause each counter to be scarfed or beveled along its chord, the scarfor bevel being of even width throughout, however the thickness of thematerial may vary.

In order to properly guide the blank to the knife I make use of a tableor platform, 0, having a groove, P, extending through it lengthwise, andprovided near its front end with a stop or shoulder, It. Atongue, S,extending down from a slide or jaw-plate, T, enteis the said groove.There is pivoted to the slide plate a jawed lever, U, provided with aspring, V, to force its longer arm upward. To the table there is fixed aset or a series ofabutments or gages, W, which may be adj ustablethereon. Between and against them the blank to be divided is to bearranged, it being placed there either by hand or by a suitable feedingmechanism. The stop R, with the inner end of the tongue S, serves toprevent the jaws from being drawn between the feedrollers. The blankhaving been duly placed on the table and seized by the jaws, is to bepressed forward into the bite of the feed-rollers by a person takinghold of the handle of the jaw-lever. On being seized by the rolls itwill be forced by them against the cutter, and drawn between and againstthe gages and split or cut lengthwise. The rolls on the tongue Sbringing up against the stop R will continue to advance the blank andwill draw it out from between the jaws.

I claim- 1.' The combination of the feed-rollers A B, the knife F, andthe two gage-plates H I, arranged relative to the feed-rolls asdescribed.

2. The knife or cutter F, provided with the shoulders 01 d, incombination with the gage plates H I, provided with the hooks e e, toengage with the said shoulders, as set forth.

3. The. hooked gage-plates H I, pivoted to the shafts of the feed-rollsand provided with springs M N to hold them in connection with the knife.

4. The combination of the gages W and the slide-jaws T U, applied to thetable, as set forth.

5. The combination of the feed-rolls A B, provided with mechanism foroperating them, the knife F, the gage-plates H I, the table 0, theabutment-s or gages W, the slide-plate T, and the jawed lever U, allbeing arranged substantially in manner and for the purpose specified.
